Am I the only one who finds Firefox unusable due to random, severe lagging/janking? I'm not talking about a little here and there, I'm talking about terrible stop/starting and dt varience, even with relatively simple projects.
I see the input lag in Canary. At first I wasn't, even with my 'torture test', a bullet hell shooter with > 2000 objects onscreen and a couple webGL shaders. No lag, 60fps, on my lowly HD4000.
However...my project resolution is low. Like, 800x600. Scaled it up by 2x, and lo and behold, there is the input lag. Plus, janking and jerking...things look terrible even at 40-50fps.
Tried in IE11. Surprisingly...it still looked pretty bad below 60fps. However, there was no input lag. Scaling the window down, everything is smooth again.
